FAQ
How does the ping work?
The tool sends an HTTP HEAD request from the server to the target URL and measures response time. HEAD requests are lightweight and do not download the full page body.
Is session data stored anywhere?
No. All monitor entries and ping history live only in your browser session and are lost on page reload.
What does the uptime percentage mean?
It is the percentage of pings in the current session that returned a successful HTTP response (2xx or 3xx). It resets when you reload the page.
Why might a site show as down when it is reachable in a browser?
Some servers block HEAD requests or reject requests without a browser User-Agent header. A 4xx response from such a server may still mean the site is online.
